Analysis of Aerodynamics on High-speed Trains

Abstract

As a matter of fact, the high-speed trains have become an important intercity transportation tool due to their efficiency, safety, and convenience in recent years. However, compared to conventional tree operation at a low velocity, the high-speed railway requires lots of new features. Among different requirement, the aerodynamic behavior of high-speed trains is crucial for their design. With this in mind, this study will briefly introduce the latest progress in the aerodynamic research of high-speed trains based on analysis of principles, simulation results as well as experimental results. To be specific, this study will analyze the train intersection, crosswind effect, tunnel effect, aerodynamic noise, aerodynamic drag, and induced wake, etc. According to the analysis, the current limitations will also be clarified and evaluated. At the same time, the future prospects will be demonstrated and proposed based on the evaluations. Overall, these results shed light on guiding further exploration of high speed trains.
